Dear all,

one gets different R values, if you re-read in the mtz written out by refmac after TLS refinement. I think this issue had been a while ago in ccp4bb, but I can't find the right track.

Here are the details.

1st run:
If we do TLS + restr. refinement in refmac
we get:
Initial    Final
R factor    0.3010   0.2170
R free    0.3175   0.2695

2nd run:
Now, if we use the same input pdb and the same input tls paramter file, but use the mtz written out by the first run, we get:
Initial    Final
R factor    0.2274   0.1903
R free    0.2482   0.2540


Apparently in the mtz file written out by the 1st refmac must contain some information that is re-read in the 2nd run. But one just defines FP, SIGFP and Rfree flags. Do FPs change in the output mtz after TLS refinement??

Any help to clarify this is appreciated.

Thanks, Guenter
